FIELD OF THE INVENTION

The present invention relates to the field of cosmetics, particularlyhair cosmetics, and relates to a solid composition which can be used forproviding a film on keratin fibres.

BACKGROUND OF THE INVENTION

Semi-permanent treatments to human keratin fibres are well known in theart. Of particular note are semi-permanent treatments that alter thecolour appearance of the hair or provide other coloured or reflectiveproperties via the use of glitter or particles. For example, direct dyescolour the hair in a semi-permanent fashion by adhering colouredmolecules to the keratin fibres. The dye can be later washed out. Hairchalks are powder-based or powdery products—typically provided in ablusher-style ‘compact’ or in pen format—that enable the user to applypigments and/or coloured particles to the hair.

A drawback of the known technology in this area is low adherence of thepigment or coloured material to the keratin fibres—it is a seriousconsumer concern that such products can make your clothes and/orbathroom dirty and/or stained. Furthermore, such pigment or colouredmaterial can migrate to the skin on your neck, shoulders and face andcause unsightly marks. Moreover, consumers wish to be able to apply.Chalk products typically provide a matt look, which may not be desiredby all consumers and would not provide a vibrant, shiny look where theconsumer desires this.

Thus there is a need for compositions and methods that provide moredurable means to adhere pigments and/or coloured/shiny material tokeratin fibres. In particular, there is a need for providing improveddeposition of these particles. Furthermore, there is a need forproviding a composition that is able to deposit a wide variety ofparticles—whether pigments, glitter or other coloured material. Inaddition, there is a need for such a composition that can be easilyapplied and distributed over the hair—for example does not result inclumping of the composition, or any kind of gluey-ness or gunky-ness ofany kind on the head of hair. Indeed, there is a need for a more naturallook to be provided by such means.

Teboul WO2014/001391A1, which published on 3 Jan. 2014 relates to a“process for dyeing keratin fibres, in particular the hair, whichconsists in applying to the keratin fibres:—at least one coat of atleast a first composition (i) comprising at least one hydrophobicfilm-forming polymer, at least one volatile solvent and at least onepigment, and then, after drying the said coat, at least a second coat ofat least a second composition (ii) comprising at least one hydrophobicfilm-forming polymer, at least one volatile solvent and at least onepigment . . . .”. Teboul does not disclose an aminosilicone polymercomprising an amino side chain. Maillefer et al in EP2090295A1, whichpublished on 19 Aug. 2009, mentions pigments in §127, but in the contextof a “method and composition for improving the drying time of hair”. Forexample, there is no teaching in Maillefer et al on depositionenhancers. Calaco et al in WO2013/085577A2, which published on 13 Jun.2013, mentions compositions and methods are disclosed for imparting along-wearing color to keratin fibers. However, Calaco et al also doesnot teach deposition enhancement.

None of the prior art teach or provide solutions that fulfil all theconsumers' needs in the present context.

Theory Behind and Advantages of the Present Invention

The inventors provide herein a solid composition. The composition issuitable for providing a film on keratin fibres following mixture withsolvent, more particularly with the aim of providing a coloured film onkeratin fibres. The composition is herein provided in solid form forease of use and storage for the consumer/stylist and ease of shipment.Indeed, in a solid context, the composition can be provided for examplein powdered or granulated form, which means that the composition keepsfor a longer time and issues with preservation and storage areminimised. Furthermore, the composition is lighter in weight and soshipment becomes more economical. Moreover, a variety of solidcompositions can be provided as a kit, each kit containing a pluralityof compositions according to the present invention wherein eachcomposition comprises a different pigment or coloured material. Hence,the consumer or stylist can select the desired colour or effect to matchthe colour of the hair in question and/or vis-à-vis other factors suchas skin tone, outfit and event.

It is expected that the consumer/stylist will provide solvent and mixthe composition with said solvent prior to application onto the keratinfibres. Indeed, the combination of film-forming aminosilicone polymer,silicone resin, ether of a water-soluble polyhydric alcohol, andselected thickening system, after mixing with solvent, results in a filmon keratin fibres, particularly human head hair, that is sufficientlydurable that it does not quickly rub off whilst on the keratin fibres,for example on the hands, clothes etc of the consumer, nor does itprovide bad hair feel, such as lumpiness, nor abrasiveness, nor weighdown the hair reducing the head of hair volume, nor unsightly globules.

Indeed, the film-forming aminosilicone polymer and silicone resin enablethe forming of a very thin, dry film, which tightly binds any colouredmaterial and/or pigment onto the hair fibres in a durable fashion. Theaminosilicone polymer and silicone resin provides an excellent film viaa crosslinking and dehydration mechanism.

The selected thickening system can help to prevent dripping of thecomposition by inhibiting capillary action, which would otherwisequickly draw the composition down the fibres and onto the floor and/orclothes of the user. Nevertheless, the thickening system, particularlythe combination of thickening polymer and deposition enhancer, providesa non-dripping composition that adheres well to keratin fibres withoutgenerating a sticky feel. Moreover, the thickening system does notdetract from the ability of the film-forming aminosilicone polymer andsilicone resin to provide the thin, dry film.

In particular, the present invention overcomes the drawbacksdemonstrated by previous developments in this area in that it is able toprovide subtle hair effects that can be employed by a much wider varietyof end-consumers in a wider variety of life contexts. In other words,the effects provided by the present invention are not limited to highlyvibrant and dazzling hair effects that are often used prior to visitinga disco or nightclub, but also provide chic hair looks that areacceptable in a business context and also not too overpowering foreveryday hair looks.

Indeed, the selected combination of features—the combination offilm-forming aminosilicone polymer, silicone resin, ether of awater-soluble polyhydric alcohol, and selected thickeningsystem—provides an excellent support system for coloured material and/orpigments, which can provide the desired effects to the hair, such asglitteriness, colour, shininess etc. Said coloured material and/orpigments may be provided separately from the composition chassis suchthat the consumer and/or stylist can select the exact the exact type ofpigment and/or coloured material desired.

Composition of the First Aspect

The composition is a solid composition. “Solid” means that the moleculesof the composition do flow over each other to take on the shape of thecontainer like a liquid does, nor do they expand away from each other tofill the entire volume available like a gas does. The composition may bein powder form. The composition may be in granule form. The compositionmay be dry, or may be anhydrous.

The composition may be in unit dose form. “Unit dose” means that thecomposition is separated into amount suitable for one head of hair orapplication. The composition may be in tablet form. Said tablet may becube or cuboid in shape.

After mixing with solvent the composition is for providing a film onkeratin fibres. The composition may be, after mixing with solvent, forproviding a film comprising pigment or coloured material on keratinfibres. The film may be a durable film. The solid composition may becosmetically acceptable.

The composition is substantially free of compounds causing precipitationof any component of the composition when the composition is in aqueoussolution at pH 5 and at 23° C.

When the composition typically comprises a film-forming aminosiliconepolymer, a MQ resin, a thickening system comprising a depositionenhancer and a thickening polymer, and a solvent, the pH of thecomposition may be between 4 and 6, preferably between 4.5 and 5.5.Examples of compounds causing precipitation of any component of thecomposition when the composition is in aqueous solution at pH 5 and at23° C. may be a basic solvent, or ionic compounds or compounds that arecationic from pH 4 to 6, preferably from pH 5 to 6 or compounds having arelative ionic strength.

Indeed, precipitation of any component of the present composition wouldhave negative side effects on the efficacy of the presentinvention—particularly in terms of hair feel. Indeed, with the exclusionof the pigment and/or coloured material that is herein intended to beimmobilised on hair, other residues on hair are not accepted by theconsumer. For example, precipitation of the film-forming aminosiliconepolymer and/or silicone resin would detract from their ability to form afilm on the hair fibres and would form residues on hair. The compositionmay be substantially free of any further ionic compounds. Thecomposition may be substantially free of any compounds that are cationicat pH 4.0 to 5.0.

Aminosilicone & Silicone Resin

The composition comprises a film-forming aminosilicone polymer, whereinthe aminosilicone polymer comprises amino side chains, and wherein theaminosilicone polymer has a weight average molecular weight of from10,000 Dalton to 60,000 Dalton. “Sidechain” (aka “side chain”) in thecontext of a silicone refers to a group being not part of the siliconebackbone nor only present on at least one terminus of the siliconebackbone. “Terminal aminosilicone” as defined herein means siliconecomprising one or more amino groups at one or both ends of the siliconebackbone Aminosilicone polymers having amino side chains are sometimesreferred to as silicone compounds comprising pendant amino groups. Theaminosilicone polymer may be not a terminal aminosilicone. Thecomposition may be substantially free of silicones having terminal aminogroups.

The aminosilicone polymer may have an amine number of from 0.1 meq/g to3 meq/g, or from 0.7 meq/g to 2.5 meq/g, or from 0.6 meq/g to 1 meq/g.

Suitable example aminosilicone polymers can be found in the followingpatent documents, which are incorporated herein by reference: DecosterU.S. Pat. No. 6,451,747B1 col. 17, 11.4-27; Hughes U.S. Pat. No.5,567,428 co1.13, 11.40-56; Gawtrey et al US2004/0010863A1, §0016 to§0039; Mahr et al US2006/0041026A1.

The solid composition may comprise from 5% to 35%, or from 10% to 25% ofthe aminosilicone polymer. The composition as applied to hair maycomprise from 1% to 15%, or from 1.5% to 5% of the aminosiliconepolymer. The viscosity of the aminosilicone polymer may be from 10 to100,000 mPa·s, or from 100 to 10,000 mPa·s.

The composition may comprise a silicone resin. Silicone resins are knownin the art. The silicone resin may be a film-forming polymer. Thesilicone resin may be an MQ resin. “M” stands for Me₃SiO and “Q” standsfor SiO₄. The MQ resin may have an M:Q molar ratio of from 0.5:1.0 to1.5:1.0. The weight average molecular weight of the resin may be from1000 Daltons to 10,000 Daltons. The MQ resin may contain at least 80mol. %, or at least 95 mol. %, of units of the general formulae below:R⁷ ₃SiO_(1/2)SiO_(4/2)in which R⁷ is C₁₋₄₀ alkyl, H, —OR or —OH radicals. The ratio of theunits of the general formulae may be from 0.5 to 2.0, or from 0.5 to1.5. The not more than 3% by weight, or not more than 2.5% by weight, ofthe radicals R⁷ may be —OR and —OH.

The remaining units of the MQ silicone resin may be units of thefollowing general formulae:R⁷ ₂SiO_(2/2)R⁷SiO_(3/2)in which R⁷ is C₁₋₄₀ alkyl, H, —OR or —OH radicals.

The composition asapplied to hair may comprise from 0.1% to 10%, or from 1% to 5%, or from2% to 4% MQ resin.

MQ resins are available from Wacker-Chemie AG, D-81737 München, Germany.For example, MQ-RESIN POWDER 803 TF is a co-hydrolysis product oftetraalkoxy silane (Q unit) and trimethyl-ethoxy silane (M unit) and canbe seen as a three dimensional network of polysilicic acid units whichare endblocked with trimethylsilyl groups. Some residual ethoxy andhydroxy functions are present. MQ resins are also available from DowCorning. For example, Dow Corning® MQ-1640 Flake Resin is a combinationof MQ and T propyl silicone resin and has the INCI name: Trimethylsiloxysilicate (and) Polypropyl silsesquioxane.

The composition comprises an ether of a water-soluble polyhydricalcohol. The ether of a water-soluble polyhydric alcohol has theadvantage that it is able to prevent the aminosilicone and the siliconeresin from forming a complex. The ether of a water-soluble polyhydricalcohol may be a non-polymeric, amphiphilic compound. Indeed, theaminosilicone comprises amino side chains, which lend hydrophiliccharacter to the aminosilicone, and the silicone resin typically ishydrophobic in nature. Thus where the ether of a water-solublepolyhydric alcohol has amphiphilic chemistry it can interact with boththe aminosilicone and the silicone resin and keep them from clumping,and also from precipitating. The composition may comprise an ether of awater-soluble polyhydric alcohol, wherein the ether of a water-solublepolyhydric alcohol is selected from the group consisting of diethyleneglycol monobutyl ether, ethylene glycol monohexyl ether, and a mixtureof diethylene glycol monobutyl ether and ethylene glycol monohexylether. The solid composition may comprise from 10% to 20%, or from 12%to 18% ether of a water-soluble polyhydric alcohol. The composition asapplied to hair may comprise from 0.01% to 20%, or from 0.1% to 10%, orfrom 0.5% to 5%, or from 1.0% to 5%, or from 2% to 5% ether of awater-soluble polyhydric alcohol. Ethylene glycol monohexyl ether has aninitial boiling point of 208.5° C. at atmospheric pressure. Diethyleneglycol monobutyl ether has an initial boiling point of 226° C. atatmospheric pressure.

A suitable product for use in the present invention is available underthe trade mark Wacker®/BELSIL ADM 8301 E by the company Wacker-ChemieAG, D-81737 München, Germany. This product contains from 10% to 20% ofpoly [3-((2-aminoethyl)amino)propyl]methyl(dimethyl)siloxane,hydroxyterminated, which is an aminosilicone. It also contains from 0.1%to 0.2% octamethylcyclotetrasiloxane and from 1% to 5% of an MQ siliconeresin. The product also contains from 1% to 3% ethylene glycol monohexylether and from 5% to 10% diethyleneglycol monobutyl ether. Said productis described in US2006/0041026A1 which is incorporated herein byreference. A similar product is Wacker HC303 also from Wacker-Chemie AG.

The thickening system comprises a deposition enhancer. The depositionenhancer is a hydrophilic and non-ionic polymer, and wherein thedeposition enhancer has a weight average molecular weight of from700,000 Dalton to 3,000,000 Dalton. The deposition enhancer is usefulfor aiding the deposition of the aminosilicone and silicone resin aswell as any pigment and/or coloured material on to the hair fibre. Inparticular, the deposition enhancer has the advantage that moreaminosilicone and silicone resin as well as any pigment and/or colouredmaterial stays on the hair fibre rather than dripping or sliding off thehair fibre. Indeed, in view of the physical structure of a head of hairi.e. a plurality of fibres that are close proximity to one another,capillary action plays a role with regards to fluids on hair. Hence, thedeposition enhancer is useful for preventing the capillary action fromstripping the aminosilicone, silicone resin and any pigment and/orcoloured material from the hair.

The deposition enhancer may conform to the formula H(OCH₂CH₂)_(n)OHwherein n has an average value of from 20,000 to 50,000. The depositionenhancer may conform to the formula H(OCH₂CH₂)_(n)OH wherein n has anaverage value of from 40,000 to 50,000. The composition as applied tohair may comprise from 0.01% to 5% of the deposition enhancer. Thecomposition as applied to hair may comprise from 0.05% to 4%, or from0.075% to 3.5%, or from 0.1% to 3%, or from 0.1% to 2%, or from 0.15% to1% of the deposition enhancer, wherein the deposition enhancer conformsto the formula H(OCH₂CH₂)_(n)OH wherein n has an average value of from40,000 to 50,000.

The deposition enhancer may have a weight average molecular weight offrom 1,000,000 Dalton to 2,500,000 Dalton.

Useful deposition enhancers are available from Dow under their POLYOXbrand. POLYOX water-soluble resins from Dow are produced and supplied aswhite, granular powders. In particular, POLYOX WSR N-60K is PEG-45M i.e.formula H(OCH₂CH₂)_(n)OH wherein n is an integer and where n has anaverage value of 45,000. PEG-45M has a weight average molecular weightof 2,000,000 Dalton. Also useful is POLYOX WSR N-12K, which is PEG-23Mi.e. formula H(OCH₂CH₂)_(n)OH wherein n is an integer where n has anaverage value of 23,000. PEG-23M has a weight average molecular weightof 1,000,000 Dalton. Also useful is POLYOX WSR-1105, which has a weightaverage molecular weight of 900,000 Dalton.

The thickening system comprises a thickening polymer. The thickeningpolymer has a weight average molecular weight of at least 10,000 Dalton.The thickening polymer is a cationic thickening polymer or is anon-ionic thickening polymer.

The co-solvent may be selected from the group consistingof unbranched or branched hydrocarbons, such as pentane, hexane,isopentane; cyclic hydrocarbons, such as cyclopentane and cyclohexane.The composition applied to hair may comprise glycerol, ethylene glycol,propylene glycol, or a mixture thereof.

The composition applied to hair may comprise an anti-freeze agent. Ananti-freeze agent has the advantage that it lowers the freezing point ofa composition applied to hair and consequently prevent the compositionapplied to hair from freezing, which can prevent any unwanted sideeffects of freezing and/or subsequent thawing. The anti-freeze agent maybe a volatile alcohol, for example a volatile alcohol having from 1 to 8carbon atoms and being miscible in water. The composition applied tohair may comprise from 0.5% to 30% of a volatile alcohol, wherein thevolatile alcohol may have from 1 to 8 carbon atoms and is miscible inwater. Miscibility in water is useful in view of the advantages of usingwater as a solvent.

The pH of the composition applied to hair may be from 3.0 to 11.0, orfrom 3.5 to 8.0, or from 3.5 to 5.5, or from 4.0 to 5.0. The pH can beuseful in ensuring cosmetic compatibility and stability of thecomposition applied to hair. For example, a too high or too low pH cancause components to precipitate, which could lead to undesirableresidues on hair.

The composition applied to hair may comprise a pH modifier and/orbuffering agent. The amount can be sufficiently effective to adjust thepH of the composition. Suitable pH modifiers and/or buffering agents foruse herein include, but are not limited to ammonia, alkanolamines suchas monoethanolamine, diethanolamine, triethanolamine, monopropanolamine,dipropanolamine, tripropanolamine, tripropanolamine,2-amino-2-methyl-1-propanol, and 2-amino-2-hydroxymethyl-1,3,-propandioland guanidium salts, alkali metal and ammonium hydroxides andcarbonates, such as sodium hydroxide, sodium silicate, sodium metasilicate and ammonium carbonate, and acidulents such as inorganic andinorganic acids, e.g., phosphoric acid, acetic acid, ascorbic acid,citric acid or tartaric acid, hydrochloric acid, and mixtures thereof.

The composition applied to hair may have a viscosity of from 30 mPa·s to1000 mPa·s. The viscosity is measured at 23° C. using a HAAKE RotationViscometer VT 550 with cooling/heating vessel and sensor systemsaccording to DIN 53019 at a shear rate of 12.9 s⁻¹. The compositionapplied to hair may have a viscosity of from 100 mPa·s to 500 mPa·s, orfrom 150 mPa·s to 450 mPa·s, or from 200 mPa·s to 400 mPa·s, or from 250mPa·s to 350 mPa·s. The composition applied to hair may have a viscosityof from 100 mPa·s to 200 mPa·s. The viscosity range is useful in view ofhelping to prevent the composition from dripping onto clothes and/orsurrounding material. Furthermore, when the viscosity is too high, thecomposition applied to hair cannot easily be mixed.

The composition applied to hair may have a tangent delta of less than 2at an angular frequency of 1 Hz at 23° C. and at 1% strain. Tangentdelta (also known as: tan delta, tan [δ], loss tangent, loss factor) isthe ratio of viscous modulus (G″) to elastic modulus (G′) and is aquantifier of the presence and extent of elasticity in a fluid. How tocalculate the tan delta is shown below:

G^(′) = Storage  Modulus G^(″) = Loss  Modulus tan   δ = Loss  Factor$\frac{G^{''}}{G^{\prime}} = {\left. {\tan\mspace{14mu}\delta} \middle| G^{*} \middle| (w) \right. = {{{G^{\prime}(w)} + {{iG}^{''}(w)}} = \sqrt{G^{\prime 2} + G^{''2}}}}$

Further information on equipment and methodology for calculating tangentdelta can be found in the Experimental section below. The compositionapplied to hair may have a tangent delta of from 0.6 to 2 at an angularfrequency of 1 Hz at 23° C. and at 1% strain. The composition may have atangent delta of from 0.6 to 1.5, or from 0.6 to 1.0 at an angularfrequency of 1 Hz at 23° C. and at 1% strain.
